For example, it's also possible to be actively taking part in the money making activity while taking unnecessary risk. A person can run his own company but recklessly making bets on the loan or spending decisions. So this is the other side of the story where they are gambling and they are actively working with their money.
That's the point. Most financial investment is really putting money into something higher risk to get a (hopefully) higher return. Most "investing conservatively" is just being a bit more wary as to what risks are acceptable.
